"This will come back as being an outstanding victory for us," Indiana coach Tom Crean said afterward. "That's an outstanding team. I certainly wouldn't bet against them this year."
Ferrell, who made three 3-pointers and also had six assists and five rebounds, scored at least 20 points for the second consecutive time. He had a career-high 26 points Friday night against Samford.
Vonleh finished with 18 points and 15 rebounds. He continues to impress, and he is the first Indiana freshman ever to record four straight double-doubles to begin a career.
Vonleh is the first freshman since Kansas State's Michael Beasley in 2007-08 to record four straight double-doubles to begin his career.
Indiana led the entire way, but Stony Brook made a couple of runs at the Hoosiers (4-0). After leading by as many as 12 in the first half, the Hoosiers led by just six at the half because of their free-throw struggles.
IU was 15-of-28 from the foul line in the first half.
But Stony Brook (3-1) never managed to crawl all the way back. The Seawolves shots just 39 percent from the field and made only three 3-pointers on 15 attempts.
Offensively, the Hoosiers kept the pressure on all afternoon. Stony Brook held its opponents to 60 or fewer points 20 times last season, and was sixth in the nation by holding its opponents to 37 percent shooting.
On Sunday, the Hoosiers scored 90 points and shot 50 percent from the field. The 90 points allowed were the most by a Stony Brook team since Nov. 11, 2011 when IU scored 96 on the Seawolves.
"Our key to the whole game was not to lose the game at the foul line," said Stony Brook coach Steve Pikiell. "The second half we just continued to foul. I think we're a better basketball team than we showed tonight, but they did a great job defending us and and made our lives very difficult with their length."
Anthony Jackson, who entered the game averaging 21 points through three games, scored only nine points on 4-of-14 shooting.
There were 55 combined fouls called in the game. Two Stony Brook players fouled out in the game.
